by John Marshall Harlan, Labine v. Vincent — Concurrence
“ It is surely entirely reasonable for Louisiana to provide that a man who has entered into a marital relationship thereby undertakes obligations to any resulting offspring beyond those which he owes to the products of a casual liaison, and this whether or not he admits the fact of fatherhood in the latter case. With respect to a substantial portion of a man's estate, these greater obligations stemming from marriage are imposed by the provision of Louisiana law making a man's legitimate children his forced heirs. ”
